PRUNING IMPLEMENT.

Specification of Letters Patent.

Patented Nov. 5, 1907.

To all whom it may concern:

Be it known that I, Lnwrs S. GorF, a citizen of the United States, residing at Spencer, in the county of Roane and State of West Virginia, have invented certain new and useful Improvements in Pruning Implements; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to priming implements and has for its object to provide a device of this class for pinning fruit trees and the like, which comprises a pruningsaw and shearing knife in one implement.

A further object of my invention is to provide a device of this class wherein the pruning knife can be quickly and easily disengaged from the saw.

A further object of my invention is to provide aprun ing knife which is so constructed that the knife will cut in both directions.

With these objects in view my invention consists in the novel construction for detachably. securing the knife to the saw, and my invention further consists in the novel construction of the knife.

Referring to the accompanying drawing: Figure 1 is a side elevation of the implement showing the knife in a locked position. Fig. 2 is a similar view showing the knife in a closed position. Fig. 3 is a vertical section taken'on line 33 of Fig. 1. Fig. 4 is a fragmentary side elevation of the removable slide, and Fig. 5 is a vertical sectional view taken on line 55 of Fig. 4.

Like numerals of reference indicate the same parts throughout the several figures in which 1 indicates the pruning implement which comprises the saw 2.

3 indicates the saw back or frame.

4 indicates the pivoted knife, 5 indicates the sliding hooked member and 6 is the handle.

The saw 2 is secured to the forward end of the frame 3 at the point 7 and is also secured at 8 to the bolt 9, said bolt passing through an opening in the frame 3, which bolt is threaded and connects a nut or cap 10 for the purpose of tightening the saw 2.

As shown, the knife 4 and the sliding hooked memher 5 are pivoted together at 11. The knife 4 has a curved blade 12 which as shown is provided with a knife edge 13 entirely surrounding the blade 12.

As shown in Fig.3 the coacting edge 14 of the hooked member 5 is square, while as shown in Fig. 2 said hooked member is slightly hollowed at 15. The edge 16 of said hollowed portion is also square as shown in Fig. 3, the edge 16 coacting with the knife edge 13 of the knife blade 12, as shown in Fig. 1.

Secured to one end of the sliding hooked member 5, as shown in Figs. 1 and 5, is a slide 17, said slide comprising a member 18 which as shown in Fig. 5 is provided with a rectangular portion 19 which passes under the saw frame or back 3 as shown. Referring to Fig. 4 it will be seen that a similar member 20 secured to the hooked member 5 extends downwardly over the saw back or frame 3, said member 20 being cut out at 21 at its lower end to accommodate the extension 19 of the member 18, said member 20 being secured to the hooked member 5 and sliding member 18 by means of a bolt 22.

Arranged in the saw back or frame 3, as shown in ment of the slide 17 as shown in 2 and also limiting the backward movement of the knife.4 as shown in Fig. 1. It will also be seen by referring to Fig. 2 that a perforation 24 is provided in a frame 3 to accommodate a removable stop 25 for locking the slide 17 against movement, thereby locking the knife 4 and hooked member 5 in a stationary position as shown in Fig. 1. This step 25 is placed in position to prevent the movement of the knife and hooked member when utilizing theimplement as a saw, as by this means all movement of the knife 4 and hooked member 5 is prevented when the saw alone is being used.

Having thus fully described my invention its operation is as follows: In order to utilize the shearing knife the limb or twig to be cut is caught in the hooked member 14. By pulling on the handle 6 the knife 4 is carried into position in Fig. 2 the knife edge 13 co-acting with the square edge 14 of the hooked member thereby cutting the limb or twig. The knife 4 being in this position a limbor twig can be cut by placing the 1101- lowed portion 15 of the hooked member 5 against the same and forcing the handle and implement forwardly, thus bringing the knife 4 into position shown in Fig. l, the'knife edge 13 co-acting with the edge 16 of the said hooked portion 15 thereby cutting the limb or twig. It will thus be seen that the knife can be brought into operation by either a backward or a forward motion of the implement.

When utilizing the implement as a saw it is essential that the shearing knife and hooked member be held rigidly in position so as not to be sliding backwardly and forwardly, and thereby causing undue wear and tear on the parts. In order to lock the knife and hooked member a stop 25 is simply inserted in the per foration 24 in the saw back or frame 3 as shown in Fig. 1, while the forward stop 23 acts as a stop for the knife 4 while in this position, and also acts as a stop for the slide 17 when the same is in position shown in Fig. 2.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a pruning implement, the combination of a saw, a frame therefor, of a shearing knife pivoted to said frame, a slidable hooked member pivoted to said knife, a slide carried by said slidable hooked member for engagement with the frame of the saw, said slide comprising a member having a rectangular portion extending under the said frame, and a similar member having its bottom edge constructed for interlocking engagement with the said rectangular portion of said first mentioned member, substantially as described.

2. In a pruning implement, the combination of a saw and a back therefor, a shearing knife pivoted to said back, said knife being provided with a rearwardly curved blade, said blade being provided with a knife edge entirely surrounding the same, a slidable hooked. member pivoted to said knife edge on the forward edge of said knife blade, said slidable hooked member being hollowed out and provided with an edge for coacting with the said knife edge of the knife on the rear edge of said knife, substantially as described.

In testimony whereof I afiix my signature, in presence of two witnesses.
